php之微信公众号开发（一）接入微信验证和创建自定义菜单

0x00首先申请微信测试公众号->记录下aapid以及appsecrt；下载官方实例demo代码；修改token值；把代码上传到服务器；把文件名重命名为index.php或其他。并用浏览器访问一下，为空则通过验证。在微信公众平台配置URL和tokenURL为公网可以访问到的ip或者地址，token随意；验证通过之后删除或注释valid方法;否则后面服务测试任何代码操作；验证通过之后就可以编写自己的代码了0x01 创建自定义菜单：首先得先去获取access_token获取方式打开浏览器请求：https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=你的appid&secret=你的secret；请求之后就可以看到你的access_token了，返回内容如下：

<span style="font-size:24px;">{"access_token":"ObNj66mQgTzQYW9ttryDRN2jTrxfo_cKWMN5lZR0rmjSOwITdabWKrjK1U8MdcuxBss40l111pNr-CzfZoaPwnoTV9gwdC7hc1hWh4ZMU6tAMaNzB5DallrgcbHGzG_uJPPjAFAUAA","expires_in":7200}</span>
